Heat shock protein 90 (HSP90) has been localised in the human endometrium, where its immunoexpression changes during the menstrual cycle. Similar studies have not been done for the equid species, so the present study aimed to describe endometrial HSP90 immunoexpression in mare endometrium. Endometrial biopsies were formalin\u2010fixed and paraffin\u2010embedded, and sections were stained with haematoxylin\u2013eosin in preparation for HSP90 immunohistochemistry. Immunostaining and morphometric analyses were performed on the epithelial lining, endometrial glands and connective stroma during oestrus, dioestrus phase and anoestrus period (<jats:italic>n<\/jats:italic>\u00a0=\u00a07 per phase or period). Immunoexpression was localised in the basal region of the epithelial cells lining the lumen. Immunoexpression was greater during oestrus than during either dioestrus or anoestrus. During anoestrus, there was little immunostaining in the endometrium, suggesting that HSP90 is involved in the functional modulation of sex steroid receptors in cyclic mares. Indeed, the function of HSP90 as a chaperone in the folding of proteins, such as steroid receptors, might explain the greater intensity of immunostaining during the oestrus and dioestrus phases, compared the anoestrus period. We conclude that, in the mare, HSP90 plays a role in endometrial function and that further studies are needed to test whether it is important in pathological conditions as endometritis.<\/jats:p>","DOI":"10.1111\/ahe.12598","type":"journal-article","created":{"date-parts":[[2020,8,10]],"date-time":"2020-08-10T19:54:16Z","timestamp":1597089256000},"page":"50-57","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Heat shock protein HSP90 immunoexpression in equine endometrium during oestrus, dioestrus and anoestrus"],"prefix":"10.1111","volume":"50","author":[{"given":"Ana","family":"Camacho Ben\u00edtez","sequence":"first","affiliation":[{"name":"Histolog\u00eda y Embriolog\u00eda, Biociencias, Facultad de Veterinaria Universidad de la Rep\u00fablica Montevideo Uruguay"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rossana","family":"Vasconcellos","sequence":"additional","affiliation":[{"name":"Histolog\u00eda y Embriolog\u00eda, Biociencias, Facultad de Veterinaria Universidad de la Rep\u00fablica Montevideo Uruguay"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3777-7708","authenticated-orcid":false,"given":"Paula","family":"Lombide","sequence":"additional","affiliation":[{"name":"Histolog\u00eda y Embriolog\u00eda, Biociencias, Facultad de Veterinaria Universidad de la Rep\u00fablica Montevideo Uruguay"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helen","family":"Viotti","sequence":"additional","affiliation":[{"name":"Histolog\u00eda y Embriolog\u00eda, Biociencias, Facultad de Veterinaria Universidad de la Rep\u00fablica Montevideo Uruguay"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9647-4731","authenticated-orcid":false,"given":"William","family":"P\u00e9rez","sequence":"additional","affiliation":[{"name":"Anatom\u00eda, Biociencias, Facultad de Veterinaria Universidad de la Rep\u00fablica Montevideo Uruguay"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicol\u00e1s","family":"Cazales","sequence":"additional","affiliation":[{"name":"Centro de Posgrados, Facultad de Veterinaria Universidad de la Rep\u00fablica Montevideo Uruguay"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Cavestany","sequence":"additional","affiliation":[{"name":"Centro de Posgrados, Facultad de Veterinaria Universidad de la Rep\u00fablica Montevideo Uruguay"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1905-7934","authenticated-orcid":false,"given":"Graeme B.","family":"Martin","sequence":"additional","affiliation":[{"name":"School of Agriculture and Environment University of Western Australia Crawley WA Australia"},{"name":"Faculty of Science UWA School of Agriculture and Environment University of Western Australia Perth Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4955-6873","authenticated-orcid":false,"given":"Graciela","family":"Pedrana","sequence":"additional","affiliation":[{"name":"Histolog\u00eda y Embriolog\u00eda, Biociencias, Facultad de Veterinaria Universidad de la Rep\u00fablica Montevideo Uruguay"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,8,10]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.3920\/CEP170020"},{"key":"e_1_2_9_3_1","volume-title":"Anatomie compar\u00e9e des mammif\u00e8res domestiques","author":"Barone R.","year":"1978"},{"issue":"1","key":"e_1_2_9_4_1","first-page":"127","article-title":"Prostaglandin E and F receptors in the uterus","volume":"2","author":"Blesson C.
